I’m a third year mechanical engineering student. Currently I have an internship at a company that provides rotary converting solutions for the packaging industry. My assignment is to re-evaluate the current tolerances on one of the machines and see if any tolerances can loosen to possibly save money and make rotary tooling more interesting for smaller volumes. I’ve done some research and I haven’t found much useful information except the different kind of analyses and small examples of 1D problems. I’m kinda stuck at this moment on what to do. Can anyone help me out?
